1. A vehicle, comprising:
at least one drive motor;
an electric converter electrically connected upstream of said at least one drive motor;
a drive controller for generating converter control signals for actuating said converter for a driving operation and a normal braking operation;
an immobilizer electrically connected between said converter and said drive controller, said immobilizer configured to prevent converter control signals, which would produce a driving operation of said at least one drive motor, from being forwarded in a direction of said converter when the vehicle is stopped or at a stop;
an alternate regulating device and a monitoring device allowing a special braking mode to be activated in a presence of an emergency braking command and in an event of which:
said drive controller is deactivated or at least a signal flow of converter control signals of said drive controller to said immobilizer is interrupted,
said immobilizer is activated, and
converter control signals producing a braking operation of said at least one drive motor are transmitted to said converter through said immobilizer by said alternate regulating device.
